The invention relates to a compound selected from the group consisting of the 3-ester and 3-ethers of 3.beta.-hydroxy-5.beta.-oestran-17-one and the corresponding 3.alpha.-epimer. On administration to humans and other warmblooded animals these compounds simulate erythropoiesis. These novel steroids are particularly advantageous in that they exhibit an unexpected low level of pyrogenicity as compared to etiocholanolone known pyrogen.
